How to Sign a PDF Document
Signing documents electronically is faster, cheaper, and more convenient than printing, signing with a pen, scanning, and emailing. Whether you need to sign contracts, agreements, consent forms, invoices, or any official document, our free online PDF signer lets you add your signature quickly from any device.
Our tool offers three flexible ways to create your signature. Draw mode lets you use your mouse, touchpad, or finger to sign naturally on the canvas just like pen on paper. Type mode converts your typed name into an elegant cursive signature using the Great Vibes font for a professional handwritten look. Upload mode lets you use an existing signature image for reuse across multiple documents.
Once your signature is created, you can place it anywhere on your PDF pages. Drag and position it precisely using the interactive preview, adjust its size with the width slider, and choose whether to apply it to all pages, only the first page, the last page, or a specific page number. The signature is embedded directly into the PDF content as a transparent PNG overlay for a natural appearance.

Signature Types and Customization
Draw your signature naturally using the mouse or touch input. The canvas responds to your actual strokes, creating a unique signature that matches your handwriting style. You can clear and redraw until you are satisfied with the result.
Type your name to generate an automatic cursive signature. The Great Vibes font creates an elegant handwritten appearance that looks professional on formal documents. You can change the signature width using the slider to match the available space on your document.
Upload an existing signature image (PNG, JPG) to reuse across multiple documents. The image is automatically centered and sized to fit the preview area. This is perfect for professionals who already have a digital version of their signature.
